Small Sample Vial Bottles with Aluminum Caps


Recommended Posts

Anyone have a source for 50-100ML glass sample vials with aluminum tops?

I purchased a few on eBay, but would like to find a provider that can sell me these in bulk. The tops for the ones I purchased also do not tighten correctly so they all leak.

Here is a link to what I am talking about:

I had a similar leak problem with aluminum caps on small bottles.
I discovered the thread pitch on the caps was different from the bottles. The caps felt tight but they didn't seat squarely on the top of the bottle.
The supplier then sent me plastic caps with correct thread pitch but they didn't seal either. The caps were too long and stopped at a ridge on the bottle neck designed for tamper evident caps
